Demonstrated Results

Participation in clinical trials helps our clinician scientists find results that improve lives.  Dr. Kee D. Kim, Co-Director of the UC Davis Spine Center, presented impressive outcomes of a ten-year cervical disc arthroplasty study, and a twelve-month study to treat thoracic spinal cord injury at the 2019 Annual Meeting of the American Association of Neurological Surgery. 

In addition to the links above, the Department of Neurological Surgery is conducting the following investigator trials:
